Description

Unreeling conveying device for abrasive cloth base materials Technical Field The utility model relates to the technical field of conveying of abrasive cloth base materials, in particular to an unreeling conveying device of abrasive cloth base materials. Background Abrasive cloths are abrasive tools based on chemical or regenerated fibers, which are produced by attaching natural or synthetic abrasive particles to a substrate. Because the abrasive cloth has the advantage of good grindability and stronger toughness, the abrasive cloth can easily polish various planes and cambered surfaces. Therefore, the abrasive cloth has a very wide application range and plays an important role in a plurality of fields such as wood processing, rubber processing, plastic product polishing, artificial leather and leather polishing, stone grinding, fine processing of glass, polishing and polishing of common steel and metal surfaces. The production of the abrasive cloth comprises the pretreatment of a base material, the application of primer, the electrostatic sand planting and the drying and curing. In the pretreatment stage of the base material, the base material is subjected to processes such as impurity removal, stretching, calendaring and the like so as to remove impurities on the base material, and the cloth is smoother. Then, the primer is uniformly applied to the base material by adopting a roller coating or knife coating process, and then the abrasive is accurately planted and attached on the base material in an upright shape under the action of an electrostatic field. Finally, carrying out stepped heating solidification through an oven to finish the preparation of the abrasive cloth. In order to facilitate conveying of the abrasive cloth base material, occupied space of the abrasive cloth base material is reduced, and the abrasive cloth base material is often tensioned and wound on a scroll. The method can obviously reduce the gap between the abrasive cloth base materials, thereby reducing the space occupied by the abrasive cloth base materials. In addition, in the conveying process, the abrasive cloth base material can be conveyed only by lifting the scroll, and conveying efficiency is greatly improved. For abrasive cloth production, two sides of a scroll wound with an abrasive cloth substrate are assembled on bearing seats arranged on two sides of a frame respectively, so that the abrasive cloth substrate can be continuously conveyed to subsequent processing equipment for removing impurities, shaping and the like for further treatment. However, manually turning and fitting a heavy reel onto a bearing housing is a very laborious task. In order to reduce the assembly difficulty, the telescopic cylinder is assembled between the bearing seat and the frame, and the bearing seat is driven by the telescopic cylinder to transversely move, so that the assembly process is simplified. Therefore, when the reel is assembled, the position of the jack of the bearing seat is needed to be firstly set, and then the telescopic cylinder is controlled to extend, so that the reel is assembled on the bearing seat. However, in actual operation, the position of the insertion hole of the spool aligned with the bearing seat is adjusted on one side, and the telescopic operation of the telescopic cylinder is controlled on the other side, so that the whole operation is still troublesome. Therefore, the cloth substrate has the defect of unreeling and conveying so as to simplify the unreeling operation of the cloth substrate and improve the production efficiency of the cloth.
